Roof window frame and method for embedding the window frame in a roof

ABSTRACT

The subject of the invention is a roof window frame with two opposite parts ( 1 ) determining the window height, having in their outer side wall on their full length a rectangular recess ( 2 ) with a supporting surface ( 2   a ) facing the roof, and having through fixing holes ( 3 ) between the frame surface above the glazing plane and the parallel supporting surface ( 2   a ) of the recess ( 2 ). The method of embedding and fixing the window frame in the roof following the invention includes inserting the window frame in an opening of matching size in the roof surface so that the supporting surface ( 2   a ) of the recess ( 2 ) in the side parts ( 1 ) rests on the rafter framing elements of the roof, and then screwing it down to these elements with screws inserted in the through holes ( 3 ) in the side parts ( 1 ).

FIELD OF THE INVENTION

[0001] The invention relates to a roof window frame and a method for itsembedding in a roof.

DESCRIPTION OF RELATED ART

[0002] Known are roof window frames with longer sides having a flat,even or lengthwise fluted surface and an even height. These windowframes are fixed to the roof by means of angle sections. One angle armis being screwed to the opposite sides of the frame on its outer edgeand the other arm is supported on rafters, purlins or the roof planking(WO 88/04348, PL-A1-340197).

[0003] There exists also a known method for embedding window frames inthe roof using assembly corner brackets, which are connected with thefour corners of the window frame by one double-segment arm each, andresting on the rafter framing elements with their second, speciallyformed arm (WO 99/35355).

SUMMARY OF THE INVENTION

[0004] The subject of this invention is a roof window frame, theopposite sides of which, determining the window height, have arectangular recess facing the roof on their full length along the outerside walls and through holes in the side parts for fixing, which runfrom the frame surface above the glazing plane to the parallelsupporting surface of the recess. The fixing holes should preferably bediverging towards the roof surface.

[0005] The method of embedding the roof frame in the roof according theinvention includes inserting it in a matching opening in the roofsurface, so as to bring the supporting face of the frame sides to reston the rafter framing elements, and then fastening it with screwsinserted in the fixing holes.

BRIEF DESCRIPTION OF THE DRAWING

[0006] The subject of the invention is illustrated in an example of itsexecution, depicted in FIG. 1, which shows a cross-section of the windowembedded in a roof.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] As shown in FIG. 1, two parallel side parts 1 of a frame, whichdetermine the window height, have a rectangular recess 2 facing the roofon the full length of the outer side wall. The recess has a supportingsurface 2 a and through holes 3 going from the frame surface above theglazing plane to the parallel supporting surface 2 a of the recess 2.

[0008] The holes 3 in the frame sides are diverging with respect to eachother towards the roof surface.

[0009] The window frame according the invention is being inserted in amatching opening of the roof surface and rests with its supportingsurface 2 a of the recess 2 on the roof planking 4. It is then screwedto the planking 4 and rafters 5 with screws inserted in the fixing holes3.

What is claimed is:
 1. A roof window frame characterized in that its twoopposite side parts (1) determining the window height, have in the outeredge, on their full length at the side facing the roof, a rectangularrecess (2) with a supporting surface (2 a) and fixing holes (3) runningfrom the window frame surface above the glazing plane to its parallelsupporting surface (2 a).
 2. A roof window frame as claimed in claim 1in which the through fixing holes (3) in the side parts (1) are arrangedin diverging directions with respect to each other towards the roofsurface.
 3. A method for embedding a window frame in a roofcharacterized in that the window frame is being inserted into an openingof matching size in the roof surface so, that the supporting surface (2a) of the rectangular recess (2) in the opposite side parts (1)determining the window height rest on the rafter framing elements of theroof and is then being screwed to it by screws inserted in the throughholes (3).
